Due to tooth preparation while treating a cavitated carious lesion or because of trauma, pulp exposition is a common event in the dental office. Many treatment modalities for this kind of lesions have been studied and evaluated. This paper presents cases in which carious teeth with pulp exposition were treated using an Er,Cr:YSGG laser. Because the use of lasers in treating carious lesions has become more common and provides certain major advantages where the vitality of the pulp is concerned, a literature review is included. Some treatment considerations are discussed, as well as future questions and objectives.
